lamp or lamps 4 and the electrical connec-v tions 5 leading to said lams. The lack of the casing is preferably cosed by means n of a rear wall6 having a suitable o ning 60 To all whom it may concern:

Be it known that I, MAUD C. FOX, a citizen of the United States,residing at New York city, borough of Manhattan, in the m inventionconsists in the. improved illucounty of New York and State of N ew York,have invented new and useful Improvements in Lam Clocks, of which thefollowing is a speci ication.

This invention relates to illuminated clocks, and proposes theconstruction of a clock having the face dial lighted from within byelectric lamps or other source of illumination. The necessity for havingthe lamps between the clock movement and face dial in order to avoid theappearance of shadows upon the face dial gives rise to the problem orendering the lamps readily accessible for the purpose of changing them,the solution of which problem is the principal object of the presentinvention.

Another object of the invention is the provision of means for windingthe clock from the front without marrng the illuminated face dial byunsightly winding stems and key-holes.

A more specific object of the invention is to slidably mount themovement, lamps and face dial relatively to the clock case, and in fixedspaced relation to each other, so that they may be drawn out asufficient distance to ive convenient access to the winding key andlamps through the space vacated by the face dial.

With the above and other objects in view,

mmated clock illustrated in the accompanying drawings, described in thefollowing specification, and particularly claimed, an

in such variations and modifications thereofY as will be obvious tothose skilled in the art Referring now in detail to the several`figures, the numeral 1 represents the clock casinV which may be of anyconfiguration and is hollow, providing a space 2 for the normalreception of the clock-works 3, the

7 through which the electric con uit 8 passes. It is not necessary,however, that the electrical connections should enter the clock from therear since the invention does not concern itself particularly with thethrough, the hands bein positioned, in the illustrative example of t einvention on the outside of the dial, the hand 13 being fixed to thesleeve 12 and the hand 14 to the usual stem 15 which extends throughsaid. sleeve. upon the dial adjacent the periphe of the latter. It is tobe understood ltliat the scope of the invention by no means limits thehands to a location exteriorly of the dial.

The bezel 10 is fixed to a carriage 16 which 35i is slidably mountedwithin the block casing. Said carriage may be-of any suitableconstruction, being here shown as comprising parallel rods 17'each fixedat one end to the bezel and extending rearwardly with- 00 in the clockcasing, the rear ends of said rods being held together by a rectan larframe 18. The two bottom rods, whic are in a horizontal plane, are-bridged over by cross pieces 19 and 20 forming supports re- -915 Yspectively, for the clock-works 3 and the lamp sockets 21.A Anoperatinghandle 22 l for sliding the carriage 16 extends through thefront of the clock casing and is secured at its rear end to the carriageor one of the 10 objects mounted thereupon, referably back of the centerof mass of sai carri so as to prevent a tilting movement of t e carriagethat might cause binding of the same in the casing. By pulling theoperating handle outwardly, the carria mcluding the bezel, lamps andclockwor is projected from the front of the clock casin The range of itsoutward movement is -mitad by the abutment of the an the clock casing.Any other'meana for lim- A dial 11 'l0k The clock numerals areinscribed,80

lar `portion V23 mi of the operating handle against the front of y l scoeof the invention.

n an illuminated clock of the character described and illustrated it isnecessary that the lamps be positioned between the clock movement andthe hands of the clock in l order to prevent the casting of a shadow ofthe movement upon the dial. This would ordinarily make it quiteinconvenient to have access to the lamps for purpose of replacement fromthe back of the clock, for

I l5 the clock-works are in the Way. It would lalso generally beimpossible to reach the lamps from the front of the clock without takingoff the hands. To avoid these difficulties I have provided the slidablecarriage to support the clock-works, lamps and face dial in fixed spacedrelation so that, by pulling upon the handle 22, the carriage comes out,the lamps and clock-works assuming the position at the front of theclock casing indicated in .dotted lines in Figure 2, being readilyaccessible through the space vacated by the bezel and face dial in theirforward movement. When the parts are in projected position the lamps maybe removed 3. and replaced without inconvenience and the handle 22 thenpressed toward the casing to restore the parts to their originalposition.

It is uite inconvenient to 'wind an electrically illuminated clock fromthe rear on 5 account of the presence of the electrical connectionslwhich are apt to become disarranged when lthe clock is bodily shiftedaway, for the purpose of winding, from the wall against which it usuallyrests. It is also undesirable to wind the clock from the front in theordinary manner by means of winding stems and keyhole bushings extendingthrough the dial, because the illuminated characterk of the latter wouldmake such construction unsightly. I have therefore devised means forwinding the dial, by arranging a key 24 on the forward side of theclock-works, said key being inthe dotted line position shown in Figure 2when the carriage is extended. To wind the clock, it

is necessary merely to pull on the handle 22 until the carriage comesout of the casing,

then to reach behind the dial and between the dial and clock casing forthe winding F key. After the clock has been wound the handle 22 ispushed toward the casing until the bezel engages its dust-proof'seat inthe latter, .the clock then having the appearance of being keyless.

Although I have thus described the preferred embodiment of my invention,it is evident that those skilled in the art may make various changes inthe construction, combination and arrangement of the several partswithout departing from the spirit and scope of the invention and Iaccordingly reserve the right of adopting all such legitimate changes.

Having described my invention what I claim as new and desire to secureby Letters Patent, is t Y 1. A clock including a casing, a slidablysupported movement having a forwardly directed windin key, saidmovement' and key being normallgy housed within said casing, and meansfor sliding said movement a sufficient distance to present the keyadjacent the exterior of said casing.

2. A clock including a casing apertured at one side, a carriage withinsaid casing mounted to slide toward said aperture, a dial normallyclosing said aperture and movable with said carriage, a clock movementmounted upon said carriage having a key directed toward said aperture,said movementvand key being normally housed within said casing, andmeans for slidin said carriage aperture-ward a suflicient istance topreen said key at the opening vacated by said 3. A clock including acasing apertured at one side, a carriage within said casing mounted toslide toward said aperture, a dial normally closing said aperturemovable with said carriage, a clock movement mounted upon said carriagehaving the hand supporting elements passing through said dial, a windingkey for said movement directed toward said aperture, said movement andkey bein normall housed withinsaid casing, an means gbr slidin saidcarriage aperture-ward a sufficient istance to pnee'n said key at theopening vlcated by said 4.
